The researches carried out aimed at assessing foliar fertilization bio stimulating effect by increasing fertilizers nutrient use efficiency and their absorption into plants. Foliar fertilizing variants NPK were formulated during the research activities on a PK type matrix base with secondary nutrients and trace elements. The nitrogen source consisted of urea and ammonium nitrate in which 6% of the total nitrogen content was added as 15N isotope to the basic PK type matrix. Agrochemical testing were carried out on ...
